Your question is one that many people are also asking. If you drop your Medicare Part D coverage now, when you do decide to enroll in a Part D plan, you will pay an increased monthly premium based on each month that you were without Medicare Part D coverage. The Premium Penalty amount is based (in part) on the price of the Part D plans and the penalty increases each year and can be more than your Part D plan premium (for example, reaching almost $1,100 for the year in 2026).
